Carmine Gallo, author of Talk Like TED, watched 150 hours of popular TED Talks and was able to pinpoint one winning trait. Speeches that involved a strong storytelling theme consistently scored higher than talks based on facts or research. Top talks shared a similar structure: Around 65% of the speech was dedicated to telling a personal anecdote, 25% referenced facts and figures, and 10% provided information to prove the speaker's credibility. Yes, if Gallo's research is anything to go by, giving a truly unforgettable presentation is as simple as following this three-step formula. No more sweaty palms!
